no guarantee that if child observes a behaviour they will definatly reproduce the action:
-there are mediating cognitive factors that will influence whether a behaviour is imitated or not.
-This means that motivations to behave in a certain way can be influenced by other sources.
-e.g. seeing a parent smoke doesn't mean the child will smoke to. It also depends on whether child is motivated to imitated the behaviour and whether they can reproduce it e.g. do they have access to cigarettes.
